Fault Descriptions
Electronics thermal relay
2 protection
These two fault codes
will be displayed when
output current exceeds
the over-torque detection
level (Pr.06-07 or
Pr.06-10) and exceeds
over-torque detection
(Pr.06-08 or Pr.06-11)
and it is set to 2 or 4 in
Pr.06-06 or Pr.06-09.
Low current detection
Limit error
Internal EEPROM can
not be programmed.
Internal EEPROM can
not be read.
U-phase error
V-phase error
W-phase error
Corrective Actions
1. Check the setting of electronics thermal relay
(Pr.06-28)
2. Take the next higher power AC motor drive
model
1. Check whether the motor is overloaded.
2. Check whether motor rated current setting
(Pr.05-01) is suitable
3. Take the next higher power AC motor drive
model.
Check Pr.06-71, Pr.06-72, Pr.06-73.
